It may have been Muse's. It was the one on Peachtree near Woolworth's, although grandad did have Brook's Brothers suits when we cleaned out his stuff cause they were nice. This would have been the 1970's, he passed in 1983. Grandad was already late 60's/early 70's when I was a kid. He was born in 1904. I was at grandad's almost every weekend and almost all summer long. I still wear his toboggan hat every other year to the home GT / UGAg game - unless it is too warm, then it just goes along for the trip. That toboggan needs another home victory.
If I were his size, I would have kept some of his sweet travelling salesman suits. I still have his Seiko. He dressed sharp to go almost anywhere.
